Based on the video, the creator completed the basic functionality of the Chrome extension in under an hour. However, the video is sped up, and the actual time spent, including pauses for thinking and troubleshooting, is likely longer. Your completion time will depend on your familiarity with coding, Perplexity's interface, and your specific requirements for the extension.
This video demonstrates how to build a Chrome extension using Perplexity AI, even without prior programming experience. The creator showcases Perplexity's capabilities in web searching and code generation using various LLMs (large language models), highlighting its advantages over other AI tools like ChatGPT. The video follows a step-by-step process of building a productivity extension designed to limit time spent on distracting websites.
